The instrument is disk-mounted type, dry and wet split structure, which is easy 
to be mounted, operated and maintained.

Backlight dot matrix type, Chinese menu, display of conductivity (uS/cm) of
water sample measured (converted into the value at 25°C) and temperature
value of the water sample

(4~20)mA buffered output signal,upper value and lower value of itscorresponding conductivity can be set freely
Upper limit alarm function of conductivity. Its contact capacity is 2A, 220V AC

Power off protection function. Data stored in the instrument can be kept even if off normal  power 

cut. It can be in measuring state dispensed with the calibration after starting up the machine again.

Make automatic temperatuer compensation for temperature coefficient of pure water and hyperp pure water

and conventional electrolytic solution. Its measuring result is accurate.

Automatic calibration, automatic switchover function of measuring range.
